I once read a very good answer regarding this, that made a lot of sense, but forgive me, I doubt I’m going to do this justice.
The issue is that we don’t use the word bless in modern English the way it once was.
the word bless has the following meanings:
bless (bls)
tr.v. blessed or blest (blst), bless·ing, bless·es
- To make holy by religious rite; sanctify.
- To make the sign of the cross over so as to sanctify.
- To invoke divine favor upon.
- To honor as holy; glorify: Bless the Lord.
- To confer well-being or prosperity on.
- To endow, as with talent.
(NOTE: I copied the above from some website, not a dictionary)
Also, there are some difference between American and British English. Check out the differences on
dictionary.com.
The point is, in older usage of modern English, saying “we bless you” is giving honor and to praise. The word bless was chosen in Old English Bibles to translate Latin benedicere and Greek eulogein, both of which have a ground sense of “to speak well of, to praise,” but were used in Scripture to translate Hebrew brk “to bend (the knee), worship, praise, invoke blessings.”
So basically, as it is with the English word “love”, this is an example of English simply lacking differentiating words for the multiple definitions of the word “bless,” allowing people to become confused regarding which definition is most applicable in the sentence.
I hope this makes sense.
God Bless
